Laboratory millimeter- and submillimeter-wave spectrum of C-13 methanol

A comprehensive millimeter- and submillimeter-wave study of the rotational spectrum of (C-13)H3OH is presented. Approximately 300 new transitions of this species were measured at frequencies up to 650 GHz, and the transitions were analyzed along with previously measured spectra using the internal axis method of Herbst et al. (1984). The resulting spectral constants allow prediction of an additional large number of transitions which should allow astronomers to identify many strong rotational lines of C-13 methanol throughout much of the submillimeter region. 23 references
